If this user has been harassing you, and you shadow-ban them, all their activities on your content will be invisible to everyone except themselves.
They will not know that they have been shadow-banned, and the goal is that eventually they will get bored while having caused no harm, since nobody saw what they posted.
You will remove your shadow-ban on this user, and their comments, messages, etc, will appear again on your content.
Such limitation improves the website as a whole by discouraging people from creating fake accounts to like their own content. Thank you for understanding!
